Background: No specific scoring system exists for the assessment of postoperative quality of life (QOL) after major abdominal surgery. This study prospectively validates PQL, a novel prospective scoring system in patients having laparoscopic or open major abdominal colorectal surgery.
Methods: Six experienced surgeons developed the questionnaire. Twenty patients reviewed and selected the most relevant questions, yielding 14 questions. One hundred patients undergoing a variety of colorectal procedures completed the questionnaire preoperatively, and on postoperative days (POD) 1, 2, 4, 8, 12, 30, and 60. Internal validation was assessed by Cronbach's alpha and factor analysis.
Results: Cronbach's alpha revealed excellent internal consistency, ranging from .84 to .94 at all time points, even at POD 1 when Cronbach's alpha was .79, demonstrating that the items in the questionnaire measured the same underlying construct. Factor analysis consistently loaded at each follow-up time on the same 2 factors.
Conclusions: Factor analysis consistently loaded at each follow-up time on the same 2 factors, designated the PQL Symptom Score and the PQL Recover Score.

Background: Dysbiosis of the nasal microbiome is considered to be related to the acute exacerbation of chronic rhinosinusitis (AECRS). The microbiota in the nasal cavity of AECRS patients and its association with disease severity has rarely been studied. This study aimed to characterize nasal dysbiosis in a prospective cohort of patients with AECRS.

Purpose: The REDUCE-IT randomized trial demonstrated a cardiovascular benefit of icosapent ethyl (IPE) but also raised potential safety signals for atrial fibrillation (AF) and serious bleeding. We aimed to evaluate the real-world safety of IPE versus mixed omega-3 polyunsaturated fatty acid (OM-3) formulations.
Methods: This retrospective active comparator new-user cohort study compared rates of new-onset AF and major bleeding (MB) among adult new users of IPE versus OM-3 in 2020-2024 US Veterans Affairs data.
Development of an image quality evaluation system for bedside chest X-ray images using scatter correction processing.

Department of Radiological Sciences, Graduate School of Human Health Sciences, Tokyo Metropolitan University, 7-2-10 Higashi-ogu, Arakawa, Tokyo, 116-8551, Japan.
In plain radiography, scattered X-ray correction processing (Virtual Grid: VG) is used to estimate and correct scattered rays in images. We developed an objective evaluation system for bedside chest X-ray images using VG and investigated its usefulness. First, we trained the blind/referenceless image spatial quality evaluator (BRISQUE) on 200 images obtained by portable chest radiography.

Background: Left ventricular (LV) dilatation and extensive scar portend a poor prognosis in heart failure (HF). The Revivent TC system (BioVentrix Inc) is used either during a hybrid transcatheter-surgical or a surgical-only procedure to exclude transmural scar and reduce LV dimensions.
Objectives: The purpose of this study was to examine the safety and efficacy of the Revivent TC® anchor system in patients with HF.

Ballet-based dance training emphasizes the equal development of both legs. However, dancers often perceive differences between their legs during balance or landing. There still needs to be more consensus on the functional difference between dominant (D) and non-dominant legs (ND).
